Benefits of technology

The present invention offers an element that is really flexible and generates electricity really well.

Problems solved by technology

Since the system utilizing the piezoelectric element uses mainly a ceramic-based piezoelectric element, there are problems that the element does not have flexibility and the element is easily broken.
However, these treatments have a problem that a large quantity of electricity is required.
Moreover, a flexibility of an element is not sufficient.
In addition, a mechanical capacity varying system is typically disposed, it is difficult to realize a flexible element.

[0196]

[0197]—Production of Intermediate Layer—

[0198]Silicone rubber (IVS4312, manufactured by Momentive Performance Materials Inc.) was applied onto a polyethylene terephthalate (PET) film, and the applied silicone rubber composition was heated to cure at 120° C. for 30 minutes, to thereby form a thin film having a thickness of 100 μm.

[0199]Subsequently, the thin film was subjected to a corona discharge treatment under the following conditions. Thereafter, the PET film was peeled. In the manner as described above, an intermediate layer was obtained.

Abstract

An element including: a first electrode; an intermediate layer made of a silicone rubber composition containing a silicone rubber; and a second electrode, where the first electrode, the intermediate layer, and the second electrode are disposed in this order, wherein a peak intensity ratio (1095±5 cm−1 / 1025±5 cm−1) of an infrared absorption spectrum of the intermediate layer varies along a vertical direction relative to a surface of the first electrode, and to a surface of the second electrode.

Description

TECHNICAL FIELD[0001]The present invention relates to an element and an electric generator.BACKGROUND ART[0002]There have been conventionally attempts for effectively utilizing the energy generated by vibrations of a structure, such as roads, bridges, and architecture, vibrations of a moving body, such as cars, and train carriages, and vibration due to human activities. As for a method for effectively utilizing the energy generated by vibrations, there is a method where vibration energy is converted into electric energy. Examples of such a method include a system utilizing a piezoelectric element, and a system utilizing electrostatic induction.[0003]The system utilizing the piezoelectric element uses mainly a ceramic-based piezoelectric element, and utilizes a phenomenon that electric charge is induced at a surface of the piezoelectric element when distortion is applied to the piezoelectric element due to vibrations.[0004]The system utilizing the electrostatic induction typically us...
